Movement of water across cells has generally been invoked to explain how the trap releases elastic energy to buckle and close. However, Ryu et al.

Drag of a shear-thickening suspension on a rotating cylinder Origine : Fichiers produits par l'(les) auteur(s)

Abstract The rheology of dense colloidal suspensions, which may undergo discontinuous shear thickening or shear jamming, is particularly difficult to analyze with conventional rheometers. Here, we develop a rheometer adapted to colloidal suspensions: the “capillarytron,” which uses the air-suspension capillary interface to impose particle (or osmotic) pressure during shear.
